One of the most emotionally-charged sites in Washington, DC is the Vietnam Veterans Memorial. The dark, black granite walls are inscribed with the 58,209 names of Americans missing or killed in the Vietnam conflict. This V-shaped memorial design draws you in and allows you to not only take in the monument's magnitude, but it also allows you to have a private, intimate moment within the monument's breadth. While you're visiting this monumental attraction, make sure you see Frederick Hart's "Three Soldiers" life-sized sculpture made of bronze that portrays three young servicemen.

The National Book Festival attracts both writers and readers of some of the world's best-loved books. Several award-winning authors head to the National Mall for this event every September to be on hand for autograph signing and seminar appearances. The kids will love meeting some of the characters from some of their favorite books as they come to life here and are available for photos.

Touted as America's First Museum of American Art, the Phillips Collection is a museum that not only presents an impressive collection of exhibits that feature impressionist, post-impressionist and contemporary American art, it also boasts a rather intimate charm. That mood is perfect for a romantic afternoon date with that special someone. Stroll through the galleries and discuss your impressions of these works and see where the conversation (and the afternoon) goes from there.

The National Archives is the ultimate historical storage unit. Every significant document and tangible piece of history is cataloged and stored here. The site houses everything from the Declaration of Independence, to the Louisiana Purchase, to the Watergate tapes. When you walk in, you'll be struck by the fortuitous, 75-foot rotunda where the most treasured documents are on display. Maps, movies, photographs, texts and more are all here, and you can delve into your own research if you are looking for something in particular.
